LEI: 213800ZBKL9BHSL2K459 OSB GROUP PLC(the Company) 2020 Annual Report and Accounts and 2021 Notice of Annual General Meeting The Annual Report and Accounts for the year ended 31 December 2020 and the 2021 Notice of Annual General Meeting (AGM) of the Company and Form of Proxy have today been submitted for inspection at the UKLA’s document viewing facility via the National Storage Mechanism at: https://data.fca.org.uk/#/nsm/nationalstoragemechanism Hard copies of these documents have been mailed to shareholders. The AGM will be held at 90 Whitfield Street, Fitzrovia, London W1T 4EZ on Thursday, 27 May 2021 at 11 am. Our preference had been to welcome shareholders in person to the meeting, particularly given the constraints we faced in 2020 due to the COVID-19 pandemic. At present, however, public health guidance and legislation issued by the UK Government in relation to the pandemic mean that there are restrictions on public gatherings and travel. In light of these measures, together with the uncertainty as to any additional and/or alternative measures that may be put in place by the UK Government and, in order to protect the health and safety of the Company’s shareholders and Directors, we are proposing to hold our AGM as a combined physical and electronic meeting. This means that shareholders and other attendees will not currently be permitted to attend the AGM in person, save for such persons nominated by the Chairman of the meeting in order to establish a quorum. Shareholders’ right to attend the AGM will be limited to participation through a video conferencing facility. Shareholders wishing to use the video conferencing facility should contact the Company by sending an e-mail to firstname.lastname@example.org no later than 11 am on Tuesday, 25 May 2021 asking for the relevant details. The Company will continue to monitor public health guidance and legislation issued by the UK Government in relation to the COVID-19 pandemic. However, given the constantly evolving nature of the situation, if it subsequently becomes possible to welcome a number of shareholders to the venue, attendance in person is likely to be restricted in terms of numbers and we would therefore still encourage shareholders not to attend the AGM in person and instead to participate in the meeting electronically via our video conferencing facility. Should it become appropriate to revise the current arrangements for the AGM, any such changes will be notified to shareholders through our website (www.osb.co.uk) and, where appropriate, by announcement made by the Company to a Regulatory Information Service.
